ABSTRACT
Biodiesel is one of the most potential alternative energy for diesel machine since
it is renewable and environmental friendly. Biodiesel can be produced by
transesterification reaction of vegetable oils or animal fats with alcohol and
catalyst addition. In this study, biodiesel was produced by transesterification
reaction of waste cooking oil and methanol with CaO catalyst of blood cockle
shells. Waste blood cockle shells (Anadara granosa) can be used as
heterogeneous catalysts for biodiesel production because it contains CaCO3 that
can be decomposed into CaO. Decomposition of the blood cockle shells as
catalyst was carried out at 900 ºC for 5, 10 and 20 hours. Types of minerals
contained in the catalyst were identified using X-ray Diffraction (XRD) and the
surface area of the catalyst was measured using the methylene blue adsorption
method, while the chemical composition of the catalyst was analyzed using X-ray
flourescence (XRF). Types of minerals in catalyst was Calcite (CaCO3),
Portlandite (Ca(OH)2) and Lime (CaO). The optimum surface area of catalyst
calcinated at 900 °C for 10 hours was 23.1674 m2/g and the chemical composition
of catalyst was 99.09% CaO. The yield of optimum biodiesel was 82.25% using
3% weight of catalyst, 1:15 of oil and methanol mole ratio, 3 hours of reaction
time and 60±2 ºC of reaction temperature. Biodiesel that obtained has 0.047% of
water content, 884 kg/m3 of density, 4.12 mm2/s of viscosity, 300 ºC of flash point
300 ºC, 0.0453% of carbon residue, 0.41 mg KOH/g of acid number, 208, 01 mg
KOH/g of saponification number, 52.38 g-I2/100 g of iodine number and 60.75 of
cetane numbers according SNI 04-7182-2006.
